Battery and Cell Block for a Battery

Abstract

A cell block for a battery includes a number of electrochemical single cells electrically connected to one another in series and/or in parallel. The single cells are flat cells oriented essentially in parallel and situated one behind the other in the cell block, and are tensioned with respect to one another by a tensioning element. The tensioning element is a temperature control plate for controlling the temperature of the single cells. The temperature control plate is situated on a longitudinal side of the cell block and thermally coupled to the single cells.
